Given:
A car is driving at a velocity of 24 m/s. Its brakes can supply an acceleration of -7 m/s².
To find:
Time taken to bring the car to a stop?
Calculation:
Let final Velocity be "v" , initial velocity be "u" , acceleration be "a" and time taken be "t":
Applying the 1st equation of kinematics , considering the acceleration to be constant:
So, time taken for the car to stop is 3.42 seconds.
